Puffin is a series of unified multimodal models advancing toward 3D world modeling. It starts from camera-centric spatial intelligence — understanding and generating the world from arbitrary viewpoints and orientations — and scales to a world model that represents worlds through three complementary native 3D world states (physics, geometry, and appearance), supporting camera-to-world understanding, camera-controllable generation, and image-/text-to-3D world generation without external perception or reconstruction modules. Each release lives in its own subdirectory of this repository:

Puffin/— Thinking with Camera: A Unified Multimodal Model for Camera-Centric Understanding and Generation (ICLR 2026) -
Puffin-World/— Puffin-World: Scaling a Unified Multimodal Model with Native 3D World States (2026)
